xtrs

Purpose:

Extract specified variables from compressed history files and write the delta values to the extracted directory.

Enter:

xtrs <label_name1> <label_name2> … [start=filename] [end=filename] [start_time=ANSI time] [end_time=ANSI time] [dir=directory] [files=file filter]

Where:

label_nameX

Specify up to 32 labels to extract from compressed history files.

start=filename

Optional. Specify the starting file name.

end=filename

Optional. Specify the ending file name.

start_time=ANSI time

Optional. Specify the start time.

end_time=ANSI time

Optional. Specify the end time.

dir=directory

Optional. Specify the compressed data directory.

files=file filter

Optional. Specify the file filter. The default is *.hst.

Example:

xtrs perf_spd Dyno_torq
The above example extracts the 2 variables from all of the compressed history files. This may take several minutes to accomplish.

xtrs RPM TORQUE oil_p start=200201010000 end=200201020000
The above example extracts the RPM, TORQUE, and oil_p variables for the 24 hour period on Jan 1, 2002.

Notes:

Limiting the extraction to a specified time period can reduce processing time if only a known range is of interest.
